Is Dry Heat More Comfortable?

I got a comment asking if dry heat was any more comfortable than heat with humidity. I suppose it is, but I can't tell the difference. In 1976 I trained for two months in the southwest US desert before deploying to Germany. I had one shower during that two months--July and August--and it was hot. It was a dry heat, but I felt very hot in a 56-ton metal container (an M60A1 tank) and after two months, I smelled like I had been hot for two months.

Yes, it is dry heat here, but two days ago when it was 108 degrees on the range (a temp update from range control) I was HOT. I suppose it makes some difference that we are in dry heat, but it does not seem to matter much with 50 pounds of gear on. It's just hot. With summer coming I am expecting a lot more dry heat in my future. I will be just plain hot.

My computer doesn't like dry heat either. It has been shutting off after an hour or less when I am outside trying to get some bandwidth near the signal towers. It turns out it can't cool itself with dry 100-degree air. So my Mac and I think alike.
